[firebase_analytics] Adblocker crashes the whole app. #335
Description
Describe the bug
A Flutter Web app will crash if the user has an adblocker enabled and <script src="https://www.gstatic.com/firebasejs/.../firebase-analytics.js"></script> can't be loaded. No widget is drawn, it crashes during the registerPlugin phase.
To Reproduce
Steps to reproduce the behavior:
- Create default app and add firebase_analytics as a dependency
- Skip the part where you would normally set up the script tags
flutter run web
Expected behavior
App should still at least launch (even though analytics won't work obviously).
Additional context
Temporary solution is to add this anywhere before loading main.js:
// Add stub so the app doesn't crash when an adblocker is active
if (typeof firebase.analytics !== "function") {
firebase.analytics = () => console.log("Adblocker detected. Created fake analytics so the app doesn't crash.");
}
